Successful vaginoscopic excision of the vaginal septum in a virgin girl of obstructed hemivagina and ipsilateral renal anomaly: Case report and review of literature

Abstract

Obstructed hemivagina and ipsilateral renal anomaly (OHVIRA) is a rare malformation that not only causes severe menstrual cramps shortly after menarche but can also lead to endometriosis and infection in the future. We report a case of OHVIRA successfully managed by vaginoscopic excision of the vaginal septum. A 12-year-old virgin girl presented to our hospital with dysmenorrhea and lower abdominal pain. OHVIRA was diagnosed using magnetic resonance imaging. Vaginoscopic surgery was performed for drainage of hematocolpos and excision of the vaginal septum. Vaginoscopic excision of the vaginal septum was performed using a resectoscope, without a vaginal speculum. The procedure was completed safely without injuring the hymen. This is the first case report of successful excision of the vaginal septum by vaginoscopic surgery for OHVIRA in Japan. Vaginoscopic excision may be one of the effective options for the treatment of vaginal obstruction.
